But just a further point that deserves to be made, it is my understanding that it is a 'bad idea' to be using mods at this point. I do not have the technical knowledge to say specifically why, nor to differentiate between the mods that "are fine" and those that "are not." Suffice to say, there are a number of very experienced Bethesda modders on these forums who have warned everyone that things like this (and worse) are the possible consequence of using mods before the GECK is released, or for that matter ever using mods that have been made using anything except the GECK.
If any of you have the expertise to provide a succinct summary of how mods work and what types are always going to be safe, whether they were made with the GECK or not, I have no desire to debate you on that, as I just do not have the expertise. Safest bet for those of us who lack such technical expertise is to just not use any until such time as the GECK is released.
Doesn't mean that using a mod that is already out is going to cause your computer to implode, your bank account to be emptied out and a mutated limb to sprout from your forehead.
But it does mean that your save games into which you've 'invested' many hours, could at some point become unplayable and leave you with no option but to restart.
ADDIT: and just to clarify: I am not in anyway "anti-mod." My Skyrim build has some 120 mods in it and I eventually plan to have a similarly hefty FO4 build. But as I learned the hard way some years ago, not all mods are 'safe' to use, and those which are out already may well be unsafe in one way or another.
